【参考范文】
I'm an 18-year old middle school student. I have been busy with my study and seldom helped my parents with the housework. Feeling quite sorry for that, I begin to think about what to do to help.
Last Sunday, when my parents went out shopping, I suddenly got an idea: why not give the rooms a thorough cleaning? Firstly I collected all the books, newspapers and other things scattered in the rooms and put them in place. Then I wiped the dust off all the furniture. After that, I swept and mopped the floors.
At this very moment, my parents came back and were quite surprised to see all the rooms tidy and floors shining. My mother gave me a hug and I could see satisfaction in her eyes. Tired as I was, I never felt so happy.
